SJ- I'm not sure I know what you're asking... But we were talking about crimping down siwash hooks. They come open eyed out of the package and you have to close the eye with pliers before you do anything with them. I rig all my spoons with a split ring and a barrell swivel, then close the siwash on the swivel. It keeps the fish from gaining leverage when they twist and either bending the hook, or ripping it out. I think the salmon university site has a diagram on making that modification.
